Bees and other insects don't have hearts in the way the higher animals do.
They don't have blood, either, but do have a clear or yellowish fluid called hemolymph surrounding their tissues which carries nutrients around the body. The insects' movements tend to keep the hemolymph moving around their body.

Why do bees die after they sting people?
If it is a good sting, the venom sac will remain with the stinger. If the bee keeps the stinger, he will live. While some bee species, like the honey bee can only sting once before dying; some bees species, like the bumblebee, can sting multiple times and still live. this is because the honey bee stinger is barbed and tears off whie stinging, while the bumblebee has a smooth stinger that does not tear off while stinging.

Why do bees die when they lose their stinger?
Generally, only honey bee workers die after stinging because their sting is barbed. Stings originally evolved to be used against other insects, and when they are they just punch a hole in the victim's exoskeleton and the bee has no trouble getting the sting back out. When it stings an animal or human the elastic skin closes around the sting and grips it. The sting mechanism is not firmly attached to the bee's abdomen so when it pulls away it leaves the sting behind together with the venom sac and the muscles to pump the venom. Unfortunately for the bee this causes other internal injuries, and the bee dies from these injuries.Other bees, such as bumble bees, have stings which are not barbed so they can easily be withdrawn from the skin.
